Addressing beyond Great Britain
For the first time, AddressBase customers can access over 1 million extra records complete with the UPRN, outside of Great Britain.
We offer the same style of licence for AddressBase Islands as existing AddressBase products. This ensures you can use your AddressBase Islands data in a consistent way across the United Kingdom and Crown Dependencies.

AddressBase Islands is available in two versions, allowing you to attach it to your existing GB AddressBase product, whether that’s AddressBase Plus or AddressBase Premium.

What are the differences between the two AddressBase Islands products?
There are two AddressBase Islands products: AddressBase Plus Islands and AddressBase Premium Islands.
AddressBase Plus Islands contains current properties including addresses sourced from Local Authorities, Ordnance Survey and Royal Mail, all provided with an UPRN (Unique Property Reference Number), for Northern Ireland, Channel Islands and the Isle of Man.The product enables the end-user to locate an address or property on a map using either X, Y coordinates supplied on a British National Grid or Latitude and Longitude coordinates provided on an ETRS89 projection.
AddressBase Premium Islands provides the most detailed view of an address and its lifecycle for Northern Ireland, Channel Islands and the Isle of Man. It has more records than AddressBase Plus Islands as it provides all the information relating to an address or property from creation to retirement.The product contains Local Authority, Ordnance Survey and Royal Mail addresses. This includes provisional addresses (proposed planning developments), and historic information (demolished properties) where available.
Ordnance Survey addresses are added to the AddressBase Premium Islands product where necessary to ensure the schema meets the core AddressBase products.
Do the Islands products contain Royal Mail's Postcode Address File?
Yes, this is a vital component of both Islands products. Royal Mail information will therefore be present where a match can be made between the Local Authority address and an address from Royal Mail.
Will commercial customers have to pay Royal Mail royalties separately?
Royal Mail royalties are included into the licence fee if you are already a Great Britain AddressBase product customer.
Additional Royal Mail royalties will apply if you aren't an existing Great Britain customer.
